Arizona Diamondbacks at Colorado Rockies: Final Score & Recap

Arizona took the series opener at Coors Field on May 17, 2026, defeating Colorado 8-6 in a game that the DiamondIQ model's estimate gave the Rockies just a 43 percent chance of winning before first pitch, a figure that fell all the way to zero by the final out. The Diamondbacks built their lead methodically, scoring twice in the third inning and adding three more in the fourth before Colorado could mount any sustained resistance. Lourdes Gurriel Jr. got Arizona going in the third with a single off Michael Lorenzen that shifted win probability 10.1 percentage points in Arizona's favor, and Nolan Arenado followed with his own single to push that swing to an additional 9.5 points. Corbin Carroll then delivered the most impactful offensive blow of the game in the fourth, connecting for a home run off Lorenzen that added 12.7 percentage points to Arizona's win probability and gave the Diamondbacks a cushion that Colorado would spend the rest of the afternoon chasing.

Colorado's most meaningful threat came in the bottom of the eighth, when Kyle Karros reached on a fielder's choice off Taylor Clarke in a sequence that added 13.6 percentage points to the Rockies' win probability and briefly tightened the contest with four runs scoring in that frame to make it 8-6. However, Troy Johnston's flyout to end the ninth inning off Paul Sewald swung the model's estimate back 12.0 points in Arizona's direction, sealing the result. Johnston finished as Arizona's top performer by WPA at plus-19.2 percent with a RE24 of plus-1.4, while Carroll led all players with a RE24 of plus-2.7 to go with his plus-16.4 percent WPA. Gurriel Jr. rounded out the top three at plus-15.6 percent WPA. On the pitching side, Victor Vodnik and Michael Soroka each contributed plus-1.6 percent WPA out of the Arizona bullpen as the Diamondbacks held off a late Colorado charge to collect the road victory.
